| Abstract: | In the Stokes approximation and on the assumption that the Péclet numbers are small expressions are derived for the capillary force acting on a droplet and for the steady drift velocity of the droplet with a given arbitrary surface distribution of the surface tension coefficient in the presence of uniform internal heat release. The thermocapillary interaction of two droplets in an unbounded external fluid and of a single droplet with a wall, due to internal heat release, is considered. Quasistationary expressions are obtained for the velocity of the droplets in such processes in the absence of gravitation. Certain limitations on the applicability of the results obtained are discussed.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 124–132, September–October, 1990. |
